On the Eastern Front, massive Soviet and German tank armies clashed in a series of battles that were unmatched in their scale and ferocity. From Barbarossa, Hitler's ruthlessly effective 1941 invasion of Russia, to the Red Army's even more destructive entry into Berlin, tanks were essential weapons; as seen in these photographs, their usage in Eastern Europe highlighted both their tremendous power and their glaring weaknesses. This book is part of a series which focuses on key conflicts of World War II, and features more than 180 captioned, archival black and white photographs, vividly documenting the war's toll on both soldiers and civilians. The accompanying text provides detailed commentary on the military maneuvers and lasting significance of the battle.
